Method: This case report presents the clinical and histopathological evaluation of dental implant therapy of two siblings with ligneous periodontitis and 5 years follow-up.
Result: Both of the patients indicated membranous gingival enlargements and mild horizontal bone loss nearby the implants. Ligneous peri-implantitis lesions were treated by initial mechanical therapy and resective surgery. Histological evaluation revealed epithelial degeneration, dense inflammation and fibrinoid accumulation in connective tissue adjacent to epitelium.
Conclusion:
Ligneous periodontitis patients may be treated using dental implants succesfully. However, increased risk of peri-implantitis should be taken into account and thorough maintenance is necessary.
